IMPROVEMENT IN FEEDING DEVICES FOR FANNlNG-MILLS.

Specification forming part of Letters Patent No. 108,154, dated October11, 1870.

To all whom it may concern: y

Be it known that I, NATHAN KIBLER, of Milton, in the county of Pike andState of Illinois, have invented a new and useful Improvement inFanning-Mills; and I do hereby declare that the followin gis a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing, forming part of this specilication.

My invention relates to tanning-mills; and consists in a new and usefulimprovement in feedin gmechanism, in connection with the hopper, ashereinafter described.

In the accompanying drawing, Figure l represents a vertical longitudinalsection of the mill on the line .r .r of Fig. 2. Fig. 2 is a verticalcross-section of Fi l on the line y y.

Similar letters of reference indicate corresponding parts.

A is the cylinder or blowing-drum. B represents the win gs, which arerevolved by crank and gea-ring in the usual manner. Unlike the ordinarytanning-mill, there is an upper and a lower channel for currents of air.C is the upper and D is the lower channel. E is the hopper. F isarevolving feeder, with wings, which scrape the wheat or other grainfrom the elastic wing G and discharge it onto the apron H, from whenceit falls onto the sieves I I' of the mill. ln falling to the apron H itpasses through the current of air in the channel C, where the chaff ismainly blown out and discharged at J. K is a spout, 'which receives anddischarges the headings and other foreign substances heavier than the'chaff from the first sieve, I. The wheat drops through the sieve I ontothe screen I', and is discharged therefrom into the air-channel D, fromwhence it is delivered, clean and ready for market, by

M N are valves in the air-channels for regulating the currents of air. 0represents the frame of the mill. l? is the crank.

S is the shoe, which holds the sieves, and is vibrated longitudinallywith the mill by the rod T from a crank on the fan-shaft. R representssupports for the shoe, which are hinged at U and fitted into recesses inthe bottom of the shoe, as seen at V, so that they vibrate with theshoe. The back side of the shoe is supported by rods, as seen at W.

By means of the feeder F the grain is discharged evenly from the hopperonto the sieves, and by the two separate and distinct air-channels,arranged as shown, the wheat or other seed is cleaned in a most perfectand expeditious manner.

The rotary shaft or roll F has wing-Scrapers arranged radially about it,so that one is always acting against the springplate G. Each wing,therefore, finds its way through the grain which lies on the incline ofthe hopper and gathers a determinate quantity for transfer into the fan,while, by its continuous contact with the spring it prevents any chokingor crowding of the grain in the vent through which it is poured upon theplate H and sieve I. An intermittent feed is thus obtained, which allowseach preceding one t0 be cleaned before its successor is admitted.

The upper channel, C, through which the cheat is forced out of the fan,is caused to diminish rapidly in cross-sectional area from the verticalplane in which the grain falls, and where the cheat is separated fromthe wheat. The object of this diminution in the size of the air-channelis to converge and increase the force of the air-current, and therebydischarge the cheat entirely from the outlet-of the fan. In windyweather this eti'ect cannot be produced with an' ordinary fan-draft ofair.

It will be perceived that my shoe S is arranged nearly in the middle ofthe fan, while the airehannels pass entirely around it, the one aboveand the other below it.

Having thus described my invention, 'I claim as new and desire to secureby Letters Patent- The winged rotary feeder F, spring-plate Gr, andhopper E, relatively arranged in a fanning-mill, as shown in Fig. l ofdrawing.

The above specification of my invention signed by me this 19th day ofJanuary, 1870.

NATHAN KIBLER.
